Time Out says

Welcome in the 'Year of the Rat' at this massive Chinese New Year celebration which will fill most of the West End with music, acrobatic and activities. Dragon and lion dances will kick things off on Charing Cross Road at 10am, shimmying down through the streets to China Town. At noon, Trafalgar Square’s main stages will spring into action with traditional dance shows, contemporary hip-hop acts and Chinese performers. Food trucks will also be stationed there and restaurants in Chinatown will have special festive treats on their menus. If you’ve got kids in tow, you can entertain them with calligraphy workshops, dressing up and performances in the Leicester Square family zone before heading back to Trafalgar Square for the closing pyrotechnics display. Xin Nian Kuai Le!
